ABSTRACT:
A pair of axially separated, radially extending annular shoulders form an annular groove on the inside diameter of an outer ring of an antifriction bearing. An adjacent axially extending eccentric surface ensures that of the outer annular shoulder continuously increases around a first arcuate portion and continuously decreases around a second arcuate portion. An annular seal between an inner ring and the outer ring has concentric circumferentially separated protrusions. An annular portion of the annular seal extends into the outer ring annular groove such that when the annular seal rotated, at least one of the protrusions abuts against the eccentric surface to lock the seal against rotation.
